{"product_id":"buckon-thermal-stress-pixel-sticker","title":"Buckon – Thermal Stress Physics Sticker","description":"\u003cp\u003eMeet Buckon, a steel rail who wants to grow in the heat but has nowhere to go. Clamped ends turn expansion into thermal stress EαΔT: about 72 MPa for steel warmed 30 K. Too much and rails bow sideways, so bridges have expansion joints. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658614018151,"sku":"18269307176649706035","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658614050919,"sku":"11218333367460358410","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658614083687,"sku":"32854608470746827689","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658614116455,"sku":"10293134229195446573","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_282cbfcc-6ecf-4338-bad9-b670b4826b9d.jpg?v=1792803643","url":"https:\/\/pixelatedphysics.com\/products\/buckon-thermal-stress-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
